RUBBING-OUT MACHINE.

Application filed .Tune 27, 1922. Serial `No. 571,326.

To all 107mm t may concern:

Be it known that I, WILLIAM C. I-IAKE, a citizen of the United States, and residentof St. Louis, Missouri, have invented an Improvement in Rubbing-Out Machines, of which the following description, in connection with the accompanying drawings, is a specification. like letters on the drawings representing like parts.

My present invention relates to shoe machinery and more particularly to a rubbing out machine utilized for laying down French binding so as to make such binding simple to fold.

Heretofore in the manufacture of shoes, one of the most difficult operations has been the putting on of French binding in a satis factory manner. No machine of which I am aware is capable of properly performing this operation, and the cost of hand labor for doing the same is so great as to be prohibit-ive if such binding is to be used in moderate priced` shoes. Heretofore, after the binding is stitched on to the vamp, it is necessary that the binding be laid out flat preparatory to folding the same either by hand or machine. As the laying out operation has heretofore been performed by hand, the expense has been such as to preclude the use of French binding on any but, highr priced shoes. With a view to performing the laving out or rubbing out operation by machine, and thus making it possible to use French binding on practically all classes of shoes, I have devised a machine forming the subject matter of the present invention. In carrying out my invention,.I have arranged a plurality of rubbing or feeding wheels rotatably mounted on shafts at an angle to each other and through which the vamp to which the binding has been stitched, is fed, the wheels rotating and the surfaces thereof moving relatively to each other to cause a rubbing down or smoothing out action of the In the preferred embodiment of my invention. one wheel may be called the feeding wheel and the other the rubbing wheel, and operating in conjunction with said wheels is a plurality of tension devices which act to. maintain the wheels in close association with each other and to cause the positive feeding of the vamp through the machine.

The' particular object of my invention is an improved rubbing out machine for rubbing out or laying flat the French binding used on the Vamps employed in the manufacture of shoes.

Another object of my invention is an improved combination of feeding and rubbing out wheels cooperating with spring tension devices for insuring smooth and positive feeding of the material through the machine. Other objects and novel features of the construction and arrangement of partswill appear as the description of the invention progresses.

y In the accompanying drawings illustrating a preferred embodiment of my invention:

Fig. 1 is a side elevation;

Fig. 2 is a front end elevation;

Fig. 3 is a plan view;

Fig. 4 is an enlarged detail of the feeding wheels taken on the line 4 4 of Fig. 3;

Fig. 5 is a side elevation of the upper portion of the machine from the opposite side to the view shown in Fig. 1;

Fig. 6 is a vertical sectional elevat-ion on the lines 6-6 of Fig. 1;

Fig. 7 is a vertical section on the lines 7 7 of Fig. 3, and

Fig. 8 is a section taken on the line 8 8 of Fig. 1.

Referring to the drawings, 10 designates a base orrstandard provided intermediate its upper and lower ends with a horizontal enlargement or extension 11 in which is rotatably mounted a shaft 12, this shaft 12 having secured theretoat one end a driving pulley 13 which may be connected by means of a belt with any convenient source of power. At the other end is secured a lmurled or toothed feeding wheel 14 of suitable diameter. The upper end of the base or standard 10 is grooved or slotted as shown at 15 in Fig. 6, and pivotally mounted in said slot by means of a bolt 16 are two plates 17 and 18. The forward end of the wheel 17 or the end remote from the driving wheel 13 extends to a point substantially over the feeding wheel 14 and is provided with a bearing (not shown) in which is rotatably mounted a horizontal shaft 19. Pivotally secured to the side of the base or standard 10 by a bolt 2O is a bearing plate 21 the f orward end of which is provided with a bearing (not shown) in alinement with the bearing on the forward end of the member 17, this bearing having rotatably mounted therein the shaft 19. At one end of the shaft 19 is secured a knurled or corrugated rubbing disc or .wheel 122,.-.one facefof which lies ,in a vertical'fplane lthat lies .at Yone side of a vertical plane passing through the aXis of the shaft 12. J At the other end of the shaft 19 is secured a flanged 'piilley "23. 4Pivotally mounted on one side of the base .orstandard 10 on a bolt 24 is a bell crank 'lever to the end of one arm 25 of ywhich v,is ,secured a spring 26, the end of the spring being .secured in .any fconvenient fmanner ,fto the base or standard 10, this spring tending fto v.move the -outerend of the .otherwarm .27 of the 'bell crank 'lever upward as viewed in .1. JThis farm '27 is gprovided with a -fslot .'28 'through which passes fa .screw l29 .that V,screws ,-into the --side ,of the r.base for standard.10,.the1sorew .and slotecooperating `Ito hold theabell crank ,lever in .fany .desired -adjusted position. At fthe extreme end of the arm 27 of the bellpranl llever is provided ;a rbolt 30 -on which 1is rotatably .mounted a flanged pulley 31. Above the pulley 'B1 and on the base or standard 10 is a bolt 82 whichmaltes an v.angle *.with'the horizontal, fanden .this bolt/82 is rotatably mounted a flanged wheel On the shaft .1.'2iand between ,the driving pulley 213 andthe V'baseforstandardLlOisseoured aiianged ,pulley -34,.-and over `the pulley-s .34, .31, 23 :and `Wheel 313 fruns an.endless fbelt 35, this-belt transmitting power ifromthe .mainshaft 1.12 to ftheffshaft 19 rand `.therefore 'to the rubbing wheel 22. The member 181is gprovided with .an l. elongated fslot whichallowsthe member to have considerable relative .'movementwith .respect to the shaft 19 and .also iwith the member 17. The ends of the members .-17 @and .18, lremote .from 'fthe Yshaft 119, vare 'jperiforated V.to Vreceive `any ysuitable means .leadfing .to fa f:treaidle` or zthe like and .byfmeansof `-wlfiich tthe said rmembers y.be :rotated about the bolt '16 .to raise y.or .lower .the lrubbngi-wheeli22.
